Don't add caption for empty titles (D7 edition)

Was looking for this exact functionality, have rerolled patch against dev in correct format and applied same change to unminified javascript.

Your patch works well acbramley. It does introduce a bit of whitespace.

1188622-image-caption-no-title.patch:50: trailing whitespace.
// Reset img styles as are added to container instead
1188622-image-caption-no-title.patch:54: trailing whitespace.
$(this).css('height', '');
1188622-image-caption-no-title.patch:57: trailing whitespace.

1188622-image-caption-no-title.patch:61: trailing whitespace.

1188622-image-caption-no-title.patch:72: trailing whitespace.

I would be happy to test it again as well. I am using more of a blunt hammer approach to getting around the issue by simply checking for whether the title attribute is defined.

Line 11 of image_caption.js

      if (typeof captiontext === "undefined") {
        captiontext = '';
      }

Very strange, I thought my patch removed the whitespace, have attempted this again.

That version applies cleanly acbramley. I confirmed on my test site as well that no span is output if the title attribute is empty.

Patch in #3 works perfectly; please commit as soon as possible. Thanks!

In addition to that I would suggest to stop processing the current image when there's no captiontext

// Get caption from title attribute
var captiontext = $(this).attr('title');
if ((typeof captiontext == 'undefined') || (captiontext == '')) {
return true;
}
// Get image alignment and style to apply to container
if($(this).attr('align')){

Thanks, committed! 81bac37
